BRlDLE-BIT.

SPECIFICATION forming part of Letters Patent No. 428,197, dated Ma 20, 1890.

Application tiled September 26, 1889. Serial No. 325,223- (No model.)

To all whom it may concern:

Be it known that I, SAMUEL L. ADAMS, J r.,

a citizen of the United States, residing at the city of St. George, in the count-y of Washington, Territory of Utah, have invented a new and useful Improvement in'Bridle-Bits, of which the following is a specification.

M y invention relates to an improved curved bit for bridles; and the object sought to be accomplished is to provide means which will more effectively bring the horse under control.

WVith this end in view my invention consists in the peculiar features and combina tions of parts more fully described hereinafter, and pointed out in the claims.

Referring to the accompanying drawings, Figure 1 represents a side View of my invention as applied to a horse and before being brought in operation; Fig. 2, a similar view showing the bit brought into use to check the horse, and Fig. 3 a plan of the bit when not in use.

1n the drawings, the reference-letter a represents an ordinary curb-bit, to which is attached my improvement, which consists of a ring I), through which the under jaw of the horse passes. free end of the arm 0 by means of a threaded bolt d, which passes through a threaded aperture e. The ring 1) passes through an eye f upon the head of the bolt cl and is retained from lateral movement within the eye by means of a pin g, which extends into a curved recess 71 in the eye of the bolt and allows the ring a to freely swing up and down. The slot in the eye is terminated by a wall 7a, which limits the upward movement of the ring a, whereby it is prevented from swinging forward in the way of the operator while ap plying the bit.

In order to prevent the bit from cutting the under side of the horses jaw, it is given an enlarged convex surface Z, which comes in contact with the outside of the horses jaw when the ring is pulled up against it by the action of the arm to which it is attached.

This ring is attached to the The preferred construction having been set forth, I will now proceed to describe its operation. When the bit is applied to a horse, as shown in Fig. 1, with the ring hanging down freely away from the horses jaw, it is then out of use and forms no check; but if the horse should require curbing the driver pulls upon the lines attached to the lower ends of the levers of the bit, which elevates the arm 0 in the horses jaw and draws the curbingring up tightly against the under side of his jaw, thereby strongly cramping and hurting him so quickly and severely as to check his speed. The screw by which the ring is attached enables the ring to be set farther from or near to the fulcrum of the bit, whereby the power brought to bear upon the ring can be increased or diminished, as desired. A further advantage of the adjustingscrew is to permit the ring -to be adjusted to horses having jaws of different sizes.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is w 1. In a curb-bit, a bit-bar having a central arm adapted to extend rearwardly into the horses mouth, in combination with a ring adapted to surround the lower jaw of the horse and being adj ustably attached to said central arm, in the manner and for the purpose substantially as described.

2. In a curb-bit, a bit-bar having a central arm adapted to extend rearwardly into the horses mouth, in combination with a screw entering the free end of said arm, an eye upon the end of the screw, and a ring held within said eye and adapted to embrace the lower jaw, in the manner and for the purpose substantially as described.
